Hi,
A couple of 18thC spontoons or I should say a spontoon and a halberd minus the axe type head although according to
https://collections.royalarmouries.o...ect-33648.html a sergeants halberd minus the head is classed as a spontoon. The 'halberd' spontoon is 7ft 5 1/2 inches and the regular spontoon is 7ft 4 1/2 inches. You can see the slot where the head would have been and secured with a screw fitting on the spear head. The one that is a dedicated spontoon has a more substantial and robust socket as you can see from the photographs. These tend not to be that thick on the ground and many seem to have had bits lopped off the shaft for various reasons so I was quite glad to obtain these two intact albeit minus the axe head.
The removable spear point has Roman numerals filed into the edge I would think to match an axe head stored or carried separately. I have attached a picture of a P1796 L.C. sabre which has the blade and scabbard filed similarly to aid matching of components.
Regards,
Norman.
